Artificial stomach reveals fluid dynamics of food digestion

In efforts to fight obesity and enhance drug absorption, scientists have extensively studied how gastric juices in the stomach break down ingested food and other substances. However, less is known about how the complex flow ...

Harnessing sound for health

When a person develops a kidney stone or a gall stone—hard accumulations of minerals and other compounds created by the body—they can experience a great deal of pain and discomfort. In more advanced cases, these stones ...

Research leads to better modeling of hypersonic flow

Hypersonic flight is conventionally referred to as the ability to fly at speeds significantly faster than the speed of sound and presents an extraordinary set of technical challenges. As an example, when a space capsule re-enters ...

Lily the barn owl reveals how birds fly in gusty winds

Scientists from the University of Bristol and the Royal Veterinary College have discovered how birds are able to fly in gusty conditions—findings that could inform the development of bio-inspired small-scale aircraft.

Aerodynamicists reveal link between fish scales and aircraft drag

The team's findings have been published in Nature: Scientific Reports: "Transition delay using biomimetic fish scale arrays," and in the Journal of Experimental Biology: "Streak formation in flow over biomimetic fish scale ...

Using physics to improve root canal efficiency

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature ...
